It's pretty and seems cool but it incorrectly imported data from Screenshots of my old app (it put all the dates for 2024 into 2023, and turned some periods into one day only) and now thinks I have 100+ day cycles. Can't figure out how to fix this as it doesn't seem to be on the main calendar, just stored somewhere. Really disappointing, it seemed so cool but now it's all just a mess.

The UI is not very user friendly. It's such a hassle to add symptoms from previous periods. Because the app will automatically jump to the current day when adding symptoms and when registering your flow the app will automatically ask when your period started and assume it's still going even though you previously filled in the correct dates. There's also not a lot of physical symptoms that can be registered.

I love the app, and the fact that my data is safe but on my phone the app is extremely slow, like minimum 1 minute for the whole app to open and all the elements of the app to appear. the scrolling down motion is extremely glitches/slow as well. I have tried un-installing and re-installing the app, clearing the cache but the problem still persists
